Professor of Chemistry
"The general research interest for my laboratory is on protein structure and how the final 3-D structure is obtained; what provides stability to a protein and how does a newly synthesized protein fold into its final shape? We use a protein from E. coli called GrpE as a model protein to try to answer questions about folding and stability because it has some common and unique structural characteristics.
Additionally, I've started exploring a new research area called protein design. I'm interested in using some of the properties we found with the GrpE protein to create a brand new protein molecule that has the potential to self assemble into a much large entity: a protein nanoring. These nanostructures will have potential use in biomedical and bioelectronic applications."

What Students Say
"Professor Mehl combines an innate ability to work informally with students and a characteristic I like to call comfortable professionalism. His ability and attitude towards working with students is best exemplified by the number of students who have expressed great interest in conducting research for him. Andrew has allowed me to follow my own direction in scientific research, while guiding me along the correct path."
